SNMP questions

Hello,
I just started with SNMP Traps on Weblogic 6.1, and I'm afraid I have some questions.
a) I configured a Guage monitor to monitor the JVM memory usage.
But I can't get it working, it never sends out a trap.
This is the config I'm using:
<SNMPGaugeMonitor EnabledServers="wb,adminserver"
MonitoredAttributeName="HeapFreeCurrent"
MonitoredMBeanName="default" MonitoredMBeanType="JVMRuntime"
Name="JVMRuntime" PollingInterval="1" ThresholdHigh="8000000" ThresholdLow="7167424"/>
Anybody has a clue?
b) Is it possible to monitor if the JDBC connections fails with SNMP? (and if
to many transactions fails due to timeouts)
tnx in advance!
Bart

Bart,
Which WLS 6.1 SP are you using? I know there have been problems with earlier SPs.
I can use the Gauge Monitor for HeapFreeCurrent without problems.
Here is the config I used:
SNMPGaugeMonitor EnabledServers="myserver"
MonitoredAttributeName="HeapFreeCurrent"
MonitoredMBeanName="myserver"
MonitoredMBeanType="JVMRuntime"
Name="HeapSize" PollingInterval="1" ThresholdHigh="5" ThresholdLow="1"/>
This does generate a trap successfully.
The MonitoredMBeanName in your case should be equal to the Enabled Server, ie.
wb (if heapfreecurrent you are monnitoring is part of server wb).

SNMP question

Am I right? (OS: windows):
1) In order to send trap we don't need anything except started SNMP service for windows.
2) In order to get possibility to make queries (polls) to agent I need to install Agent and have EM Grid Control?
3) I don't have any MIB files till I will install Agent.
Thanks.

The agent needs to interface to the snmp service by setting up a snmp peer agent, and a snmp encapsulation service.
This is described in a separate snmp manual.
The purpose of sending snmp traps is having them adressed by applications like Tivoli, Openview or the like.

SF300-24P - SNMP question

Hi,
I've a script that does the check of port status asking OIDs
.1.3.6.1.2.1.17.4.3.1.2
.1.3.6.1.2.1.17.4.3.1.1
.1.3.6.1.2.1.2.2.1.8
after a firmware upgrade, all these OIDs are not available.
for example:
snmpwalk -v 2c -c public 192.168.1.197 .1.3.6.1.2.1.17.4.3.1.2iso.3.6.1.2.1.17.4.3.1.2 = No Such Instance currently exists at this OID
I also tried to follows procedures like:
http://www.cisco.com/en/US/tech/tk648/tk362/technologies_tech_note09186a00801c9199.shtml
using the community string indexing (I don't think that it applies to small business switches) but for desperation...
Have you any suggestion?
Thank you very much in advance,
and sorry if it's an already asked question, I've tried the search button, but without finding a definitive answer.

SNMP Question for NX-OS on 5000 series

I'm trying to use SNMP to talk to my 5000 series switches (with 2148 switches in tow). I'm trying to do it in such a way as to represent the full hierarchy of the switch, along with the status of each of the ports.
Currently, I'm using the entPhysicalTable to determine what switches are connected, which modules are in place, and the ports that on the modules. However, I'm having trouble finding a map and/or algorithm for getting from these rows to the proper rows in the ifTable. I thought that I had a handle on the process, but have since hit a snag with different versions of firmware. Some of my switches are running 4.1(3)N1(1a), but a few are still on 4.0(1a)N2(1a). This seems to be making a difference as to how the ports are ordered. There also seems to be a difference depending on the expansion modules that I have on my 5000. If I'm using a N5K-M1008, those ports are mapped differently than if I've got a N5K-M1404 in place.
Each time that I think I find an answer that I can use, another variable cuts me off.
Is there a consistent approach to this mapping? Even if it is firmware dependant?
Thanks,
Matt

Each vendor has their own firmware with their own bugs and problems and not yet implemented SNMP architecture related hazards.
If your mainly interested in finding out port mappings, LLDP is a wonder protocol for finding out just that. It's a lot simpler than SNMP. Just turn on LLDP and use the LLDP commands to find out what's what.

Questions on Receiving SNMP Traps

Hi:
- I have more questions on receiving SNMP traps:
1) the OEM plug-in can receive traps now, but when I click the metric, I see:
Error getting data for target test20. Exception: ORA-20216: ORA-06512: at "SYSMAN.EMD_MNTR", line 817 ORA-01403: no data found ORA-06512: at line 1
- the push descriptor looks like:
<PushDescriptor RECVLET_ID="SNMPTrap">
<Property NAME="MatchEnterprise" SCOPE="GLOBAL">...</Property>
<Property NAME="MatchGenericTrap" SCOPE="GLOBAL">6</Property> <Property NAME="MatchSpecificTrap" SCOPE="GLOBAL">31</Property> <Property NAME="MatchAgentAddr" SCOPE="INSTANCE">target_ip</Property>
<Property NAME="EventsnChasFanIndexOID" SCOPE="GLOBAL">...</Property>
<Property NAME="ContextsnChasFanDescriptionOID" SCOPE="GLOBAL">...</Property>
<Property NAME="SeverityCode" SCOPE="GLOBAL">WARNING</Property>
</PushDescriptor>
- is the Key Property needed ?
2) The alerts for some reason do not filter back to the all targets home page.
- When I click the Home tab and goto to the 'All Targets' pane, I do not see the alert generated by the OEM plug-in.
- What I am doing wrong ?
3) Is it okay to receive traps with the metric usage set to either: HIDDEN or HIDDEN_COLLECT ?
- Does this cause the errors I see in Q 1) ?
Thanks
John

Hi John,
Can you post the full definition of the metric? You would need to use the Key property for each key column in the metric description.
With the SNMP receivelet you can set up definitons for data points or alerts. I would assume (as I've never tried this ;) that if you set up the definition to be a data point, you would see data from the All Metrics page. To me, it wouldn't make sense for a metric that used the PushDescriptor SNMPTrap to have data to be viewed as the result of the SNMP trap coming is would be an alert. I will have to look into that. My gut reaction is that a metric with PushDescriptor SNMPTrap shouldn't even appear on the All Metrics page ...
To be clear are you saying that you don't see the Warning number under "All Targets Alerts" increase by 1 when you SNMP trap is caught and alert is generated? When this occurs do you see the alert on the target instance homepage?
In regards to HIDDEN and HIDDEN_COLLECT, I don't know what effect they would have on a metric defined for an SNMP trap to raise an alert. You definitely wouldn't want to use HIDDEN as this setting is for temporary metrics that are used in the caclulation of other metrics. HIDDEN metrics are not collected (or hence uploaded to the OMS) and don't appear in the UI. HIDDEN_COLLECT are collected, but do not show up in the UI and are not uploaded. I've never used this settings with SNMP trap metrics that are for alerts. If your metrics for the SNMP trap alerts do show up on the All Metrics page (I'd have to get something set up to look at this), then it could make sense to use the HIDDEN_COLLECT as the alert would still be generated, but the metric itself wouldn't be shown in the UI.
Let me find out the expected behavior from someone on the agent team.

Questions on Weblogic SNMP

Hi,
I have managed to start WLS snmp agent in Solaris2.7 but I have a couple
of questions on the following:
./snmpget stage57 public
.1.3.6.1.4.1.140.600.20.1.20.10.115.116.97.110.100.97.108.111.110.101.11.115.101.114.118.101.114.45.55.48.48.49
1) Why do I need to put in so many trailing numbers in order to snmpget
data from an object? What do these number mean? Any documnetation on
them? Based on the WLS MIB tree .1.3.6.1.4.1.140.600.20.1.20 is where
the serverState is located.
2) Why did serverState always return 1 (which means UP) even 2 minutes
after I brought down the server on port 7888 and ran the above on the
command line? In the startSNMPAgent.sh file, I have specify the port
number in this line "$JAVA weblogic.SNMPAgent -password 123 -serverURLs

LMS 3.2 DFM-all devices QUESTIONED-SNMP Timeout

I imported 26 devices to DFM. All devices became QUESTIONED, error is SNMP timeout. Here are the troubleshooting steps that I tried:
1. rediscovered devices
2. deleted and rediscovered devices
3. increase snmp timeout settings
4.re-entered snmp strings in device credentials
But I still get the same result.I noticed that devices become questioned so fast.Any advise on this?

Hi,
What version of SNMP you are using on these 26 devices ?Try to do the following:
- Go to Device Center
- Select one device for test
- click on "check device credentials", select SNMP according to the version you are using.
- See the results.
May be you get more technical and detailed information about the SNMP timeout error. I have already experienced some problems using SNMP v3. The problem was resolved when I configured the SNMP v2c instead of v3.
Also, I suggest you to try do "SNMP walk" test in the Device Center. If you get some results reading, for example, the value of "sysObjectId", just verify the Credentials Settings in DCR. You can edit the Credentials trhough the Device Center -> Edit device credentials.

Wando N. Rocha

SNMP Configuration question

Question on SNMP Read-Write String ...

Hi,
My question is that if I am using an SNMP read-write community string on the device, would Prime LMS still require
the logging credentials of the device via ie) telnet/ssh ?
The reason how I undertand this as long as the SNMP manager (Prime LMS) and the agent (end device) have the same read-write community,
couldn't the Prime LMS just write to the device without the standard logging credentials ? or is the logging credential of the device is a must for it
to push configuration to the device ?
Pls advise.
Many thanks.
Cheers,
- sn -

Even though the SNMP communication is there between device and LMS, it is not possible to configure any device using SNMP, except for the RW variable and OIDs, which are limited in their scope.
It is not possible to configure, but to copy configuration to or from device using SNMP. See the following document to check further:
http://www.cisco.com/en/US/tech/tk648/tk362/technologies_configuration_example09186a0080094aa6.shtml
Many people use this manual process to copy configuration from device using SNMP, edit it and copy back to device to make configuration changes, but ideally no NMS server does it and LMS is no exception.
It uses transport Layer protocols like telnet/ssh to communicate with device like a normal user to configure commands, which in this case is done by Netconfig job.
For more details see :

Question to SNMP

Folks,
I'm having some issues with the MIB sysName.
Normally with this MIB I will get the FQDN like ""router1.domain.com"" if I have configured the "hostname" with router1 and the "ip domain name" with domain.com.
If I remove the "ip domain name" statement from the config I expect a sysName without the domain like ""router1"" (in this example).
This work pretty well with 98% of my CEs but not for some connected through an internet based circuit.
At this CEs I get back a FQDN like ""router1.kornet"" or ""router1.no-domain-set.bellcanada"" ... so it looks that the ISP add something .. question is now to to eliminate this?!
any idea?
thx

do you get any errors in the server logfile ?
Also, about your other question: the current agent cannot be extended to support addditional metrics. However it can co-exist with other SNMP agents running on the same machine which may support custom defined metrics.

SNMP mib Persist question

Hi All,
I have a WS-C3750-48TS stack of 4 Members (all same type).
I have for Monitoring purpose an Powersupply and FAN Monitor.
The Indexi for Member 4 has been changed from 4003 to 4004 after a change of the master Switch (from SW1 to SW2) as well as a reboot of SW4 and SW1.
Now I read that the SNMP mib Persist command is available and that the data has to be written to the NVRAM .
the config guide says:
Usage Guidelines
After entering the snmp mib persist command, you must enter the write mib-data command to save MIB persistence configuration data to NVRAM.
Here is were my question starts.
If I write the data to the NVRAM, which NVRAM will be written?
will this prevent the change of the index after a reboot of the non master switch?

Looking at the error message "The Network Adapter could not establish the connection" , It appears hostname and port may be incorrect. Review the targets.xml under E:\oracle\product\10.2.0\db_1\SAP_solman_SDB\emd and
emoms.properties under E:\oracle\product\10.2.0\db_1\SAP_solman_SDB\config folder to make sure host ( sap_solman) and port (1527) are correct.
As far as setting the environment variables goes, you can go to control panel -> system -> advanced -> environment variables and set the ORACLE_HOME and ORACLE_SID

WLC 2006A SNMP v1 support Question/Bug

With SNMP v1 enabled on the WLC-2006A device:
SNMP v1 Mode.... Enable
SNMP v2c Mode... Disable
SNMP v3 Mode.... Disable
All I can see are SNMP v2 traps being sent... no SNMP v1 traps.
Is this a bug or what?

With the following set:
SNMP v1 Mode.... Enable
SNMP v2c Mode... Disable
SNMP v1 traps should be sent, but they are NOT.
Likewise,
SNMP v2 traps should NOT be sent, but they are.
The management tool being used only supports v1 traps and thus ignores the v2 traps which are being sent!
IF upgrading will resolve the problem, then an upgrade is in store, but if upgrading WON'T solve the problem, then that's a hit-and-miss changenineering (not engineering) method which may or may not resolve the problem.
Thus if upgrading WILL solve the problem, customer will allow it, otherwise they won't.
So is it a bug, is it per specification or what? And will the upgrade (to what version?) resolve the problem.
Without knowing the cause of the problem, one cannot guarantee the upgrade to what ever version will fix it.
If it's a bug and a later version has fixed that bug, then fine.
If it's an older specification which has since been modified and a newer version has changed that older specification to work properly, then fine.
Otherwise, it's just a guess!

[Q] WLS SNMP Agent questions?

Hello, all
I am attaching the weblogic.properties, startWebLogic.cmd and
startSNMPAgent.cmd
I started the weblogic server 5.1 on port 7001.
Then started the SNMP agent using the command
"%JAVA% weblogic.SNMPAgent -password system -snmpPort 161 -serverURLs
t3://210.182.160.120:7001 -community public -debugLevel 3 -trapDestinations

WLS SNMP Agent questions ?

1- What version of SNMP does the WLS SNMP agent use ?
( IMO, it is the SNMPv2)
2-Is it possible to use the WLS SNMP Agent to register our own MBean ? ( is
there a Factory , or an entry in JNDI ? )
3- In the case, I develop my own JMX Agent, is this agent clusterable ? or
should I have several JMX Agent running , with Dynamic MBeans( because we
don't know on which machine in the cluster a MBean is ) ?
